Viscose staple fiber is a regenerated cellulose fiber made from dissolving pulp. Because it is produced in staple form, it can be spun into yarns and used in textiles, nonwovens, and blended applications.
VSF is viscose staple fiber in short fiber form, while VFY is viscose filament yarn in continuous filament form. Rayon yarn refers to yarn made from rayon or viscose fiber and is usually tracked in yarn market pages. Users should match the term to the fiber form and downstream use.
